Heres a subject that I have to deal with because while I hope someday to have 100 seaters, i only have a 16 seater and so if 20 people show up, I cant stack them up in my sunroom, they might eat all my snacks. So Im converting the bottom part of my old barn (central heat all summer, icy air conditioning all winter).. Anyway I'll cover more of this as it takes shape, but exhibits can go here .. stuff for sale... other educational theaters etc .. a tv with a dvd player..

To kick off the weird exhibits phase, I had been toying with this idea of a 24/7 fixed scope a kid could see something to whet imaginations .. so going shopping in the junk here, wa la! a nascent 12 inch pseudo reflector with an incredible 1200X view of saturn! gare

High gloss WHITE, would be my choice.

I think a traditional HPA pipe fitting stand is called for, perhaps you could use an old tractor wheel for part of the mount, maybe as the right ascension axis?

Wonderful job on the display!

I'd be partial to a nice cotton fabric print of outer space objects...planets, moons, spaceships etc.

Now if it were a real scope???????

Steve
mrgare5050
Yes I'll probably build a simple mount to show how home guys (i was once called an astro hillbilly!) do it. Ive thought of Orange, and White .. I hadnt thought of the space motif! .. Im sortof partial to blue though.... hmmmm g

Excellent!!! You have a lot of room there. Continue your great work. If people don't come, it's their loss.

What a great place for conversations about ALL things astronomy! I can just see myself sitting back sipping on a steamy cup of coffee with a slice of apple pie and vanilla ice cream along with the rest of all you'se guys!

It's too bad we weren't all closer together. I feel as though I know all of you and we have get togethers at lest once a week. Gare, your area has a very comfortable home feeling were people can get together and just be people. Places we all need more of.
mrgare5050
all the cool planetarium people seem to be in arizona, but theres a few in ohio and tenn too! actually im from illinois and michigan more than tenn.

working on my pseudo scope today, i was TEMPTED to paint the tube celestron orange and cobalt blue, but took owens suggestion and went for gloss white so i can incorporate that old unitron 10x40 finder we talked about.. thats the mount from one of my 2.4 refractors collecting dust... g

That's a great way to get the smaller kids interested in astronomy. It would be interesting to see the Andromeda galaxy illuminated with black light.

Again MORE CLEVER things from Gare!

You really do have a lot of space in there. That's the first time I've seen pictures of your visitor's center. You were meant to be a MUSEUM PERSON. The pseudo-scope is very cool.

Gare ANOTHER inexpensive public item is to use old bathroom scales with your own calibrations as in: What would you weigh on the Moon? On Jupiter etc? You can add more as you find more used scales....

Just take the scales apart and glue your own "dial" on them.

GREAT idea on the scales MM, would have never thought of that, but it was a favorite exhibit at the old adler. The fake scopes were a byproduct of bringing home huge vinyl poster displays from the sprint store where I work, turning them over they provide huge white projection surfaces which can be overlapped and stapled over my dome surface. AND they come in large cardboard tubes! g

I thought I had a 'crazy stuff' board, this must be it - most of the stuff from years past is also past, but I've never let go of that 'make something' or 'sell something' for planetarium groups - so the other day I unearthed this old sheet of paper that was an Edmund 'Dipper Finder' - Edmund of course means nothing to todays generations, but to older guys perhaps it brings back many fond memories .. anyway, I built a souped up Dipper Finder, and might use this as a do it yourself thing for kids - i never really liked general planispheres because they were too much detail in too small a package, but just finding the DIPPER has a charming simplicity. Of course you can add (as I did here) more stars, (more stars!), horizon trees, more times etc.

I don't think that I've ever seen that. It is something that could be printed on a sheet of paper (or card stock as that would be better) and with a brad and a pair of scissors make a great project for kids. It could be a handout for free as I doubt one could charge much for it. I have a little "gift shop" on the edge of my control console which has the Edmund full size planisphere star chart as from my perspective it is complicated enough to be worth $5. It comes with a little 16 page booklet explaining how it works. If you buy it from Edmund it is $3.95 with $1.75 shipping so mine is a better deal. With a bulk package of 25 I can get them for $2 each thus making a little for the planetarium. I also sell my daughter's book as well as "copper coin" memberships so there is a little in the "gift shop". One day I might make a dvd or how the projector works but that is a lot of work for probably such a small return.

I probably should spend some time on a web site but that is for after the first year. The first year will tell a lot.
mrgare5050
RW you've got the gift shop spirit! I once made a planertarium Christmas ornament, I'm looking for it now. Going to try a few more 'finders' like the Dipper finder - maybe the Orion finder etc

Im going to try to sell a 'constellation' lamp on Craigs List . my scheme is, punch stars in an inverted bowl which becomes the shade, buy an old lamp at Goodwill, put a colored bulb in it, and list it as a space lamp for 20 bucks.

you think it will sell? i DONT want to 'ship' it, and set up Pay Pal and all that. I want someone to come OUT HERE and buy it, and see the planetarium too... whatchu think?

Someone will probably buy it. A GCL for $20. I'd start with only one to see how it sells.

exactly - now im wondering if a 'planetarium' shade alone to be added to your existing lamp would sell - although lamps I've found have a surprising number of shade holder configurations, and most used ones at thrift stores are missing their screw on 'nut' or whatever its called .. this will definitely be throw one thing at a time at the wall and see if anything sticks. i havent given up on the home star projectors, but if something that can be used in a lighted room like a lampshade would work, it would be so much easier...
Ron Walker
How about a template made out of cardboard that could be placed on a white lampshade with holes for the stars and then spray painted with black paint. Once dried, the template could be moved to the next lampshade to repeat the process. You would have a quick assembly line way of making them. True it would be black stars on a white sky but look at how many "projectors" do that now. It would be more of a star globe then projector but still useful.

ANYTHING 'could' work, i've set up a small factory out back so will begin producing ..

Lamp-tariums. PINK will be a big color, as girls are heavily into science these days, said the man who knows nothing about it. hopefully.

I like "Lamp-tariums". You can also add a small cup so that one can plant a flower.

Do you have a star lamp sales sign by the road or is it only for planetarium visitors? You can add that to your next free posting.

it might GENERATE planetarium visitors and a few dollars, plus scratch that 'punch starholes' itch. i have zero expectations though, in line with everything else related. i have this mythical kid in mind with SOMETHING in their room, on their nightstand, in their childhood memory. if its not a visit to a planetarium, maybe it can be some cakebox like i had. its also an excuse to spray paint old junk cool colors....

I havent finalized an initial offering because i cant decide what kind of shade looks best - an existing shade, a PAINTED existing shade, a bowl shade, a custom made shade

i'm in the shade....

"Haunted house dark sheds" makes me think you're turning into the "loud hatcheted man".

Loud Hatchet Man - great plot device for Chapter 4, out no doubt before the sun go down!

but thats not why im here. the subject is exhibits and gift shops and merchandise for all ages

im revisiting my 90s collection - i had these mugs, featuring an accurate depiction of the 10 foot dome shed hanging off the back of the barn!

I like that, how many did you have made and did any sell? The nice thing about that is all you need do is put them on a shelf in the gift shop. You really need to get a dome up and operating again.

I'm open if somebody WANTS to come out - no ad still Spring though. I remember giving away a half dozen or so to class teachers, it was mostly kids back then with no need of a coffee mug. I'd like to order more though, I wonder how much they are these days. A guy in the Spyglass Network sent me that design. I'd be tempted to do more funny mugs .. I cant think of anything funny but .. you know like

Planetarians Dont Need Sunglasses or something.
Ron Walker
The trouble with so many of these things is they are fun but can't really help the planetarium unless they make money to allow the procurement of good junk like projectors that can be used in presentations under the dome.

The cost for the cheapest mug would be around $4 each in quantities of 75 down to $1.40 each in quantities of 1,000. Also there is shipping and a set up charge for each run. For the number of sales I could generate hardly worth it for me.

I plan on trying just about everything you can think of - you can go in Goodwill and just buy shades for a few bucks, plus make them out of a variety of bowls etc. You could probably make them out of Earth Globes.

Square shades have the advantage of 1 side per season. Now there are dilemmas though - no top means, where do you put the circumpolar stars? I think its more about identifying the shapes rather than accurately depicting the whole sky. Ive thought of possibly painting a shade, then using a nail or other sharp object with a straight edge and drawing the connecting lines between stars - the lines would then glow . How many size holes? Different size shades would require different star templates

If i find something that sells i could hone in on that, but how can i do THAT if im buying as available used stuff - in that case, no two will be alike . thats probably where this is going. so that means, if proof of concept is positive, i might want to build up an inventory and give people a choice - but then do you advertise them separately? Again i want people to come here, buy one, and see the planetarium or even do a quickie demo show.

Ive blended colors on plastic bowls - you can create nice blue/green effects etc. What color BULB to put in - colored bulbs make them seem more exotic, but LED bulbs can be expensive, those party bulbs are cheaper. touchup paint can be required on banged up old lamps, and the PARTS to hold the shades can be a problem .. it can get quite involved.

but I am

The Lampster .... or I am .... LAMPMAN ...... or ....

see that double green one, that will be LAMPO UNO. Im keeping the pink one. also below, the planetarium effect
